于慧敏信号与系统第二版第五章部分习题的matlab代码... (And systems in Huimin Xin No. Part Second Edition Chapter Exercises matlab code ...)

有关雷达的MATLAB仿真资料！！！！！！！！！！！！！！！(MATLAB simulation of the radar information! ! ! ! ! ! ! ! ! ! ! ! ! ! !)

用matlab对离散系统的时域分析，得到其特性曲线(Using matlab for time-domain analysis of discrete systems, by their characteristic)

用matlab打开AVI文件，裁剪视频、转换成二值化视频并输出文件(Using matlab to open the AVI file, cropping video, convert the binarization video and output file)

这是一个关于垂直腔半导体光放大器（VCSOA，微腔光放大器的一种）中的双稳态曲线计算程序，用Matlab语言写成，可执行。程序是根据VCSOA中的速率方程（Rate Equation）编写的。从曲线上可以看出随着输入功率Pin的变化VCSOA的输出功率Pout的双稳态曲线，是进一步研究该问题的基本素材之一。(This is a computation program for calculating the bistability activity of the vertical cavity semiconductor optical amplifier, which is based on the rate equation in VCSOA. This code is a basis for further investigating other activities in VCSOA related to bistability. )

最速下降法又称为梯度法，是1847 年由著名数学家Cauchy 给出的，它是解析法中最古老的一种，其他解析方法或是它的变形，或是受它的启发而得到的，因此它是最优化方法的基础。这里给出其Matlab源程序。(The steepest descent method, also known as gradient method, was in 1847 given by the famous mathematician Cauchy, it is the oldest analytical method one, other analytical method or its variants, or inspired by it obtained and therefore it is the basis for the optimization method. Here are its Matlab source.)

将一个512×512的lena.bmp图像进行DCT变换，对得到的DCT系数按8×8块进行分层（分三层），重组填充得到新的系数矩阵，结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

说明：  Matlab数理统计方面的图书源码聚类分析，希望对您有用(Matlab mathematical statistics, cluster analysis of source books, I hope useful for you)

低通和高通滤波程序，是常用的图像预处理程序(lowpass filter program and highpass filter program)

使用matalb软件，利用递推阻尼最小二乘法进行参数辨识，并改变噪声的强度，即 a*ξ(t)（0<a<1），分析、比较一般递推最小二乘和递推阻尼最小二乘方法的优缺点 ；(Use matalb software, the use of recursive damped least square method for parameter identification, and change the intensity of noise, that is a* ξ (t) (0 <a<1），分析、比较一般递推最小二乘和递推阻尼最小二乘方法的优缺点 ；)
